and State of South Carolina, have inventedV certain new and useful Improvements in Nut and Bolt Locks; and we do hereby declare the following to be a full, clear, and exact description of `the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had. to the accompanying drawings, and to the letters 4and figures of reference' marked thereon, which form a part of this specification.

-This invention relates to certain new and useful improvements in nut and bolt locks and it has for its object to produce a device of'this character which will serve to positively lock a nut upon a bolt against the possibility of itsbeing accidentally released.

'Io these Aends and to such others as the invention may pertain, the same consists in the peculiar construction, novel arrangement, combination and adaptation of parts,

i all as will be more fully hereinafter described, shown in the accompanying drawings and then specifically defined in the appended claim.

The invention is illustrated in the accompanying drawings which,'with the numerals of reference marked thereon form afpart of this specification and in which Figure 1A is a sideelevation of the nut locking device embodying our invention, the

parts being shown as locked in position and- Fig. 2 is a longitudinal section view in` which vthe nut is shown as removed from its seat.

Reference now being had to the details of the drawings by numerals, -1 4is a boltA provided at one of its ends with 'a head 2, the

free end being screw-threaded as shown at 3. 4 is a nut, internally screw-threaded to engage the -right hand threads 3 upon the bolt, the hollow interior ofthe bolt 1 being provided with lefthand screw threads 5.

6 is a screw or bolt having a'diameter,

equal to the hollow interior screw-threaded chamber 7 of the'bolt l, the shank portion of the screw or bolt 6 being provided with a left hand screw thread 8 adapted to engage the interior threads 5 within the chamber of the bolt 1. v The enlarged end 9 of the shank portion of the bolt 6 is provided at its inner end with an interiorlyleft hand threaded'chamber 10, the thread 11 within the bolt head being'adapted to engage-the left hand threads 12 upon the outer 'end of the nut 4.

Having thus described our invention, what we claim to be new and desire to secure by Letters Patent is:

In combination with a bolt having a head and a circumferentially threaded shank portion, said bolt 'being hollow and the wall interiorlythreaded, a nut fitted over the lcircumi'erentially threaded part'of the bolt and having a shoulder which is .circumfer-v entially threaded, a nut having an integral screw pro]ecting therefrom for engagement with the interior threads of the bolt, and -a i head with a flange interiorly threaded and adapted to fit over the threaded shoulder of said nut. g

In testimony whereof we hereunto alix our signatures in presence of two witnesses.
